- Kitchen extract systems with no recent grease readings
TR19 inspection in Bitchet Green, done properly
A pre-clean survey looks at the whole system, from canopy to discharge. Access is checked along the full length, and grease readings are taken at set points. The work covers deposit thickness tests, access surveys and wet film thickness tests, and the jobs we see most are cleaning intervals that may not suit the kitchen and parts of the system left out of past cleans.
In a village or hamlet like Bitchet Green, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Aftercare tips
So the system stays in good health:
- Don’t box in or cover duct access panels
- Store grease readings where your insurer can see them
- Flag changes in how much frying the kitchen does
- Look out for grease drips round the canopy edge
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Keep all TR19 records together so you can produce them quickly.
Kitchen extracts in Bitchet Green
There are about 4 restaurants, cafés and canteens within roughly a mile and a half of the centre of Bitchet Green, according to the Food Standards Agency’s register. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Bitchet Green is covered by Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Sevenoaks council that sends environmental health officers to food businesses in Bitchet Green. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
Bursars and site managers at schools such as St Lawrence Church of England Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens, like those at hospitals such as Sevenoaks Hospital (about 2.8 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Where a hall near St Lawrence, or anywhere in Bitchet Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Common questions in Bitchet Green
Do you work at weekends in Bitchet Green?
Yes, evening, overnight and weekend work is normal for us. The work in Bitchet Green can fit around your hours. Your opening times are the first thing we ask for.
Which fire and rescue service is responsible for Bitchet Green?
Kent Fire and Rescue Service is the fire and rescue service for Bitchet Green. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you cover Bitchet Green?
Yes. We cover Bitchet Green and the rest of Kent, as part of our work across South East England and London. For a fixed quote, call 0345 646 2711, or send details by email.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.
What is grease thickness testing?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Why it’s worth doing now in Bitchet Green
Post-clean verification shows whether the system was left the way the certificate says, before the next clean is due. Our emergency line runs 24/7, but a planned visit to Bitchet Green is calmer for everyone.
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. If the van will struggle with a lane or gateway near Bitchet Green, let us know and we’ll plan around it.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
Getting a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
How the job changes from site to site
Canopy and plenum
We look over the canopy, inside and out, and note where grease has gathered.
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Readings show if the interval is right.
